Yeah, the owners manual says to shift into 5th at 41 mph, but if you watch that shift indicator while you're in 4th, it'll give you the UP arrow when you get to 31 mph. It seems kinda low to me, but Ford isn't telling us their rationale for that guidance and why it's different from the book. Obviously, they're concerned about gas mileage, but why the two different guides is puzzling.
